Compact, Easy-to-Integrate Embedded Storage
With their high-performance, high reliability and low cost-per-megabyte, HGST
USB flash products meet the design requirements of embedded devices,
including industrial PCs, point-of-sale (POS) terminals, networking equipment
and automotive diagnostic applications.
HGST USB Flash Modules (UFMs) are plug-and-play USB 2.0 embedded
storage solutions that simplify design and speed time-to-market. The 10-pin
connector is a common interface found on many embedded system boards,
and the standard mounting hole makes it easy to secure the module for
rugged applications.
HGST USB Flash Drives (UFDs) are removable thumb drives with a high
electrostatic discharge (ESD)-rated enclosure for applications that require
Network Equipment-Building System (NEBS) Level 3 compliance. The
standard USB 2.0 Series A interface provides designers with the flexibility of
a true plug-and-play portable embedded storage device.
Fast, Reliable and Cost-Effective
The USB standard is one of the simplest and most widely used protocols for
embedded applications. Its widespread support, combined with its small size
and low power, makes it an ideal boot device, code storage, or data logging
solution where space, power and cost are key design considerations.
Features and Benefits
Feature / Function Benefits
High Performance Up to 33MB/s sustained read and up to 26MB/s sustained write
Rugged Design UFM: High tolerance to shock, vibration, altitude and temperature protects against mechanical failures
UFD: Rugged ESD rated enclosure (tested for immunity from 8kV contact and 15kV air) protects against mechanical
failures as a result of electrostatic discharge
Full data-path protection Enhanced data integrity with full data-path protection and built in ECC engine that corrects up to 12 bits/512-Byte errors.
High endurance Advanced wear-leveling and block management with guaranteed 2M program/erase cycles
Simple integration USB 2.0 compliant. Plug-and-play for fast time-to-market
Physical interface UFM: Choice of standard 2x5 pin (2.54mm height) or low-profile (2mm) 9-pin connector for integration flexibility
UFD: Standard series A connector
